Application filed May 2, 1901. Serial No. 58.479. (N model.)

To all whom, it ntcty concern: United States Patent No. (36*,790, dated De- Be it known that I, JONAS NORTHROP, a cember 25, 1900. The toothed wheel a on subject of the King of Great Britain, residing the disk d, the cooperating detent-pawl 6 at Hopedale, in the county of Worcester and pivotally mounted at e on the stand A the 55 State of Massachusetts, have invented an Imstop It for the endmost filling-carrier b of provement in Filling-Replenishing Mechanthe series in the feeder, and the finger mare ism for Looms, of which the following descripalso as in said patent and operate as therein tion, in connection with the accompanying set forth. drawings, is aspecification, like letters and I have herein shown a clutch-device for ef- 60 IO figures on the drawings representing like fecting rotation of the feeder, said clu'tch parts. comprising a ratchet-like member 0, rotatable This invention relates to thattype of auwith the feeder and herein formed by maktomatic filling-replenishing. mechanism for ing a series of ratchet-teeth in' the hub a looms wherein a plurality of filling-carriers, while the cooperating or loose member of the 65 each containinga supply of filling, are mountclutch is shown as a sleeve 0 0r pawl-carrier ed in a rotatable feeder or hopper which is surrounding the ratchet c and loosely mountintermittingly rotated to bring the fillinged on the hub a between the toothed wheel carriers one by one into position to be en- 61,8 anda collar 20, secured to the hub.

I

Should there be one or more filling-carriers absent from the feeder, the impetus imparted to the feeder by or through the contraction of the spring S will be sufficient to continue the rotative movement of the feeder until the gap is passed and the next filling-carrier engages the stop h.

Various changes or modifications may be made in the construction and arrangement of parts herein shown and described without departing from the spirit and scope of my invention, one practical embodiment of which forms the subject-matter of this specification and the 'subjoined claims.

Having described the invention, what I claim, and desire to secure by Letters Patent, 1s

1. A rotatable filling-feeder to hold a series of filling-carriers, a transferrer to engage and remove the latter one by one, a clutch to rotate the feeder, means governed by operative movement of the transferrer to set the clutch and independent means to actuate the clutch and rotate the feeder when the transferre r returns to normal position.

2. A rotatable filling-feeder to hold a series remove the latter one by one, a clutch mem-' ber rotatable with the feeder, a cooperating loose clutch member, a connection between the latter and the transferrer, to set the loose tached ratchet, a cooperating pawl, an oscillating'pawl-carrier coaxial with the feeder, a transferrer, a flexible connection between the pawl-carrier and the transferrer, to retract the former when the transferrer operates, and an actuating-sprin g connected with the pawlcarrier to move it forward and thereby rotate the filling-feeder when the transferrer returns to normal position. i

6. A rotatable filling-feeder having an attached ratchet, a cooperating pawl, an oscillating pawl-carrier coaxial with the feeder, a transferrer, two oppositelyextended flexible bands attached to the pawl-carrier, one of said bands being secured at its free end to the transferrer, to retract or set the pawl-carrier -when the transferrer operates, and a spring fixedly secured at one end and at its other end connected with the free end of the other band, to move the pawl-carrier forward when the trausferrer returns to normal position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JONAS 'NORTHROP.
